BUMPER FOR MOTOR VEHICLES.

Application led August 9, 1924. Serial No. 731,170. i

To a7] Ulom tonu'l/ concern.'

.Be it known that I. Enxns'r (ALAssr, a subject of the. King of Italy,residing at Brooklyn. in the county of Kings and State of New York, haveinvented new and useful Improvements Bumpers for Motor Vehicles, o'tVwhich the 'following is a specification.

This invention relates to improvements in bumpers for motor vehicles andhas for its primary object, the provision of a pair of sections, one otwhich is stationarily mounted to the chassis frame of an automobile, andthe other of which is yieldably carried by the first said sectionslforward thereoffor relieving the impact' againstthe rigid sectionshould the bumper come in contact with another vehicle or other object.

Another object of the invention resides in the provision of a bumperwhich includes adjustable attaching means for adapting the bumper tovehicles of different widths.

Another' object of the invention is to provide a bumper Which is simplein construction, cheap of manufacture, and easy to apply and removefroma motor vehicle.-

. With these and other objects in View, the

invention resides in certain novel construc- Y tion and combination andarrangement of Darts, the essential features of which are hereinafterfully described, are particularly pointed out in the appended claims,and are illustrated in the accompanying drawing, in which z- Figure 1 isa top plan view of my improved bumper shown applied to a motor vehicle.

Figure 7 is a top plan view of a slightly modified form of my invention.

Figure 8'is a front View of the form shown in Fi re 7.

Figure 9 1s a vertical sectional View on the line 9-9 of Figure 8.

Referring more particularly to the drawand to which my improved bumper11 is shown attachedbyattachiug means 12.

My improved bumper is constructed of lat material and includes a'relatively rigid section 13 and a'yieldable section 14 which' issupported by the section 13 and which is disposed forward in advance ofthc said section 13.

As hereinbeforc mentioned, the sections are constructed of a flat springmaterial but it is understoodA that the material may be other motorvehicle from passing over and i under the members should the same comein contact with another motor vehicle equipped with the usual style ofbumper.

The yieldable section 141 is mounted on a plane between members 15, andcomprises a part 19, which lies at the rear of the members 15 and whichextends approximately the entire length of the members as clearly shownin Figure 1 of the drawing. The

ends of the part 19 are bent upon the body I topi-Ovide spaced attachingportions 20 for the attachment of one end ota pair of identical parts21. The parts 21. are positioned onthe front side of the members 15 andhave their other ends bent inwardly as at 22 for attachment to the part19y by bolts 23, disposed on opposite sides of the center. Sjmilaribolts24 connect the other ends of the part 21 tothe attaching portion 20. Forclosing the space between the parts 21, I provide a brace member 25which is attached to the parts'21 by suitable bolts 26. i'

The attaching means 12 hereinbetore mentioned comprises a C-shapedbracket 27 which is adjustably mounted on the members 15 and which isheld in the adjusted position by a bolt 28 which passes through the bodyof a bracket and lthrough the ends of same, which ends are Vbent aroundthe members 15 to provide eyes 29. Lock nuts 30 co-aet with the bolt 28and retain the bracket in its position of adjustment upon the members15. Brackets 31 having hook portions 32 engage the llanges 'of thechassis frame and the bracket 27, and are connected to the bracket by abolt 33 and securing nuts 34. The bolt 33 passes through a slot 35 inthe bracket 27 and through aligned slots 36 in the brackets 31 as shownsection comprising ,/a

in Figures 5 and 6 of the drawing. By providing the slots in thebrackets, it will be Aseen that the bumper will be adjusted to variousangles according to the angle desired. By having the brackets 27slidable on the memberl, itis possible to adjust the attaching means toa chassis frame of various widths.

From the foregoing description, it will be seen that when the bumpercomes in contact with another vehicle or obstacle, the section 14: willbe the .first part of the dcvice to strike, and as the same is formed ofrelatively springy material and is secured at its ends to the section15, will move inwardly with respect to the section 13 thereby taking upthe initial impact. The cross bars 17 limit the inward movement of thesection 14 and when the same has reached the limit of its inwardmovement, the section 13 will then begin to pick up the impact. Thesection 13 is also of a springy nature and will yield a slight distancewithout causing breaking of the parts.

In Figures '7 te 9 inclusive, I'have shown a slightly modified form ofbumper which is identical to that shown in the preferred form with theexception of the section 13 which comprises roundedxmembers or bars 15connected b cross cpieces 17 and cleats 37 by bolts an nuts-38'?? Thecross pieces 17 and the cleats 37 are bolted to the'section 14" as at39. The manner of operation is identical to that of the preferred formso that a description of the sameis not believed necessary.

While I have described what I deem to be the most desirable embodimentof my invention, it is obvious that many of the details may be variedwithout in any way de arting from the spiritof my invention, an Itherefore do not limit myself to the exact details of constructionherein set forth nor to anything less than the whole of my inventionlimited only by the appended claims. f

What is claimed, as new isz- 1. A bumper including a relatively rigidair of 'vertice ly spaced members and a yieldable section disgsection,sai

posed forward of said nidixs'ection and supported thereby, means orlimiting the inward 'movement of said yieldable section,

said means embodying spaced vertical memsection, attaching means forconnecting said section to the chassis frame of a motor veh lcle,andyieldable means carried by said rigid section forward of the same,and

means on said rigid section for co-action .with said yieldable sectionfor limiting the inward' movement-of the last mentioned section, saidatt-aching means being adjustable longitudinally upon .said rigidsection.f

3. A bumier including a 'relatively rigid section comprising a f-pair ofspaced members,v cross pieces connecting said members, a yieldablesection carried by said rigid section,and disposed for movement betweensaid members, said cross pieces serving to limit the inward movement ofsaid yieldable section.

4. A bumperv including a relatively rigid section, said sectioncomprising a pair of spa-cedY members, cross pieces connecting saidmembers, a yieldable section carried by said rigid section, and disposedfor movement between said members, said cross pieces servincrto limitthe inward movement of said iyieldable section, attachin means carried ysaid members and a justable thereon.

l5. In combination with the ends of a chassis frame of a motor vehicle,of a relatively rigid structure, compound adjustin means for attachingsaid structure tosai ,chassis frame and a yieldable means extending thelength of the rigidV section and forward/thereof.

6. yA bumper including a relatively rigid section, said sectioncomprising a pair-' ef spaced members, cross pieces connecting saidmembers, a yieldable section carried by said rigid section, anddisposedfor movement between said members, said cross pieces serving tolimit the vinward movement of said yieldable section, and attachingmeans including a C-shaped bracket member adjustablyV mounted on saidspaced members and adjustable yclamping j means for co-action with thechassis frame of a vehicle.

In testimony whereof Ihave atlixed my signature.
